Question

A student said that 42% of 78 is 45. Is this answer reasonable? Explain.

Answer 1

No because 42% of 78 is 32.76

Explanation:

Answer 2

Answer: Sample response: 42% can round to 40%, and 78 can round to 80. 40% of 80 is 32, so 42% of 78 should be about 32. 45 is much greater than 32, so the answer is not reasonable.
